A cube has sides of length 5 cm. Find the total surface area of the cube.
Please explain as well, as I struggle with surface area.

150 cm^2

Step-by-step explanation:

Keep in mind that the dimensions of the cube are identical in 6 directions.  This means that the surface area of the bottom is 5 cm by 5 cm, yielding the area 25 cm^2.  The top has the same area, so considering top and bottom we get a total surface area of 50 cm^2.

Likewise, the total surface area of the sides together is 50 cm^2.  The total surface area of the front and back together is 50 cm^2.

Thus, the total surface area of the entirre cube is 3(50 cm^2), or 150 cm^2

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

a is the correct
